( Figs. 44–46 ) Description. — Male. Body length 4.0 mm; LFW 2.88 mm . Color: head and mesosoma black; metasoma, clypeus and mandible dark castaneous; antenna, legs and palpi castaneous; wings subhyaline. Head : mandible bidentate. Clypeus trapezoidal. First four antennal segments in a ratio of 27:11:10:10, segment XI 1.5 X as long as broad. Frons strongly coriaceous, punctures large, shallow, separated by 0.5–1.5 X their diameters. LH 1.02 X WH; WF 0.59 X WH; 1.24 X HE; OOL 1.17 X WOT; DAO 0.33 X WOT; posterior ocelli distant from the vertex crest 1.67 X DAO, frontal angle of ocellar triangle acute. Vertex slightly straight, corners rounded. VOL 0.5 X HE. Mesosoma : thorax strongly coriaceous, with punctated smaller and more distant each other than those of frons. Pronotal disc 0.57 X length of mesoscutum. Propodeal disc 0.6 X as long as wide. Fore femur 3.0 X as long as thick. Metasoma : tergite II with pair of very shallow lateral depressions, each one with tubercle flat­topped, with pit on the top, with dense tuft of long hairs, tubercles slightly closer to the median line than the lateral margin of tergite II. Hypopygium with median stalk 1.4 X as long as plate, posterior margin straight. Genitalia ( Figs. 44–45 ): paramere as long as basiparamere, apex rounded and thin. curved slightly inward, dorsal margin straight and ill­developed, ventral margin concave above; volsella with cuspis with apex acute, digitus with large basal projection; aedeagus with ventral ramus longer than dorsal body, laminar, surface vertical, angled medially outward, ramus thin with apex wider and rounded in lateral view; dorsal body with two pairs of apical lobes, outer pair angled medially outward, apex with two sharpened teeth directed downward, ventral margin dilated medially ( Fig. 46 ), inner pairs stout, membranous and hairy; apodeme extending beyond the elliptical genital ring.

Plaumann col. ( MCZH ) . Variation. — Metasomal tergite II with tuft smaller and hairs less hairy, two specimens with the apical margin of outer lobe slightly serrated. Etymology. — The specific epithet refers to the shape of ventral ramus and outer lobe of aedeagus, which resembles two joined hands. Distribution.Brazil ( Espírito Santo , Paraná , Santa Catarina ).
